...LATE MONTH RAIN PUSHES MAY ABOVE NORMAL FOR PRECIPITATION...

NEARLY TWO AND A HALF INCHES OF RAIN ON THE LAST TWO DAYS OF MAY
HELPED PUSH MONTHLY PRECIPITATION TOTALS OVER 6 INCHES AT SOUTH
BEND. THIS ALSO MOVED THE MONTHLY PRECIPITATION TOTALS FROM THE NEAR
NORMAL CATEGORY TO THE WELL ABOVE NORMAL CATEGORY. IT WAS ALSO A
RELATIVELY WARM MONTH WITH TEMPERATURES AVERAGING NEARLY 4 DEGREES
WARMER THAN NORMAL. THE LAST DAY OF THE MONTH HOWEVER WAS VERY COOL
WITH DAYTIME TEMPERATURES STAYING IN THE 50S.

THE AVERAGE MONTHLY TEMPERATURE WAS 63.2 DEGREES...3.9 DEGREES ABOVE
NORMAL. THIS RANKED TIED FOR THE 19TH WARMEST MAY ON RECORD. THERE
WERE JUST 9 DAYS WITH AN AVERAGE TEMPERATURE BELOW NORMAL. THE
HIGHEST TEMPERATURE WAS 86 ON THE 7TH AND THE COOLEST WAS 37 ON THE
19TH AND 20TH. THERE WERE 12 DAYS WITH A HIGH TEMPERATURE OF 80
DEGREES OR WARMER BUT ALSO 4 DAYS WITH A HIGH TEMPERATURE BELOW 60.

MAY WAS CLOSE TO NORMAL FOR PRECIPITATION HEADING INTO THE 30TH BUT
2.00 INCHES OF RAIN FELL AT THE AIRPORT ON THIS DAY AND ANOTHER 0.46
INCHES FELL DURING THE MORNING OF THE 31ST. THIS PUSHED THE MONTHLY
TOTAL PRECIPITATION TO 6.01 INCHES...2.18 INCHES ABOVE NORMAL. THIS
RANKED AS THE 14TH WETTEST MAY ON RECORD. WITHOUT THIS LATE MONTH
HEAVY RAIN...MAY WOULD HAVE RANKED AROUND 56TH WETTEST. THE 2.00
INCHES OF RAINFALL ON THE 30TH WAS ALSO A RECORD FOR THAT
DATE...BREAKING THE PREVIOUS RECORD OF 1.53 INCHES SET IN 2004.

THERE WAS NO SNOWFALL RECORDED DURING THE MONTH.
